Executive Summary

This vulnerability exists in OpenClaw versions before 2026.2.22. It is an allowlist bypass issue in the system.run exec analysis feature. The problem occurs because the system fails to properly unwrap environment and shell-dispatch wrapper chains. As a result, attackers can route execution through wrapper binaries such as 'env' or 'bash' to smuggle malicious payloads, effectively bypassing the intended allowlist restrictions.
